【Example】

 Embodiments will be described below with reference to the drawings. A joint block according to an embodiment of the present invention will be described with reference to FIGS. 1 (A) and 1 (B). These are arch-shaped blocks having a semicircle with a center radius r of 27 mm. The main body 1 is formed by molding and joining the main body 1 in the longitudinal direction into halves so that the main body 1 becomes hollow. The cross section of the block body 1 has a substantially square shape as shown in FIG. The block main body 1 is provided with buttons 2 and 3 which are fasteners for joining blocks, and male buttons 2 and female buttons 3 are attached to the respective surfaces. In FIG. 1 (A), a male button 2 and a female button 3 are attached to both end surfaces 4 and 5 of the main body 1, respectively. Also, the arched surface 6 of the block body 1 has a female button 3 in the center thereof, the radially outer surface 7 has a male button 2 in the center thereof and the opposite arched surface thereof. The female button 3 is attached to the center of the button.

The male button 2 of this joining fixture is fitted so as to sandwich the projection holder 21 having the positioning projection 22 in the mounting recess 61 provided on the arched surface 6 of the block body 1. The united body 25 is arranged and fixed by a screw 27 to a fixture 29 located inside the block body 1. An outward protruding portion 26 is provided at an end portion of the fitting body 25 projecting to the outside. In addition, the female buttons 3 are arranged in the mounting recesses 71 provided on the radially outer surface 7 of the block body 1, and are arranged at the same intervals in the circumferential direction on the outer peripheral portion that is substantially flush with the outer surface 7. A positioning recess 31 is formed at a position so as to engage with the positioning projection 21 of the male button, and a recess 32 into which the fitting body 25 of the male button 2 located at the center is fitted has a radius inside the outside. An inward protruding portion 33 protruding inward is formed so as to engage with the outer protruding portion 26 of the male button 2 to avoid easy disengagement. Further, the female button 3 arranged in the mounting recess 71 is fixed to the fixture 29 located inside the block main body 1 with the screw 35, similarly to the male button 2.

Further, the fitting of the buttons 2 and 3 is not only easy to be attached / detached even by an infant of about 3 years old, but also fitted so that they can be engaged with each other even in a joined state. Has been In this engaged state, when the joined block bodies 1 are rotated by the engagement of the positioning projections 21 of the male button and the positioning recesses 31 of the female button 3, the engaging positions are different. Thus, the block body 1 can be held at that position until a predetermined rotational force is applied.

The block main body differs from that shown in FIGS. 1A and 1B in that the radius of the arch-shaped main body is different from that shown in FIGS. 2A and 2B. Has been done. This block body 100 has a center radius r'of 54 mm and the same structure as the block body 1 except for the overall size. As shown in FIG. 3, as shown in FIG. It can be joined in combination with the one shown in FIG. Then, as shown by a dotted line in FIG. 3, the direction can be changed.

In the block main body 1 and 100 having the above-described structure, when the male button 2 and the female button 3 attached to both side end surfaces 4 and 5 are joined to each other, each arch-shaped block is formed. Since the main body 1 and 100 are continuous, a curved shape can be obtained, and a shape that is intriguing to an infant can be freely obtained, which is different from the linear shape as in the conventional block. In the joined state, the block bodies can be freely rotated while maintaining the joined state until a certain amount of rotational force acts on the block bodies, and the shape can be changed in the three-dimensional direction. It is easy to handle even for infants.

Since both buttons 2 and 3 of the joining fixture are provided at the central portions of the arch-shaped side surfaces 6 on both sides of the block body 1 and 100 and the arch-shaped outer side surface 7 in the radial direction, Not only can it be connected continuously, but it can also be branched and connected, and can be extended in three dimensions to develop into different shapes.

Further, when a plurality of sets of a plurality of arc-shaped block bodies 1 and 100 having different radii are used as the joint blocks, if a plurality of sets are provided or each set is color-coded, each block is further colored. It can be of interest.

Further, although the block main bodies 1 and 100 have a quadrangular cross section, other shapes such as a rectangle such as a rectangle, a circle, an ellipse, and the like can be used even if they have such shapes at the time of joining. When combined, it can give more shape changes.
